I am hoping to put in an offer on a house as it's the right place and right timing for various reasons. I am usually really cautious with money, and have a smallish mortgage on my current house. The house I want to buy is just about affordable, but I would double my mortgage debt and repayments. I could just about do it, but it's a huge house, and it would all be much easier if I rented out a room or even a floor. AIBU to consider buying this house, if I can only comfortably afford it by having to rent some of it out? Thanks for any opinions
